Bray is expected to retain his job as the team's primary return specialist but could be headed for a role in four-receiver sets after failing to catch a pass as a rookie in 2015. "Quan has had two really good days as a wideout," said coach Chuck Pagano said. "He can make plays and make-miss ability out in the open field." Bray is competing for reps alongside undrafted rookies Marcus Leak and Chester Rogers. It's a thin group at wideout behind starters T.Y. Hilton, Donte Moncrief and Phillip Dorsett.

The ex-Raider made it almost the entire year on the Bills' 53-man roster but caught only 13 passes in 14 games. It's disappointing considering how in flux the Bills' receiver corps was. Going on 30, Holmes' offseason outlook is uncertain. Neck injuries are the trickiest in football. Holmes is under contract in Buffalo for the next two years.

Bills coach Sean McDermott said Zay Jones underwent knee surgery last week and will miss the rest of the offseason program.

Jones also underwent shoulder surgery in January. McDermott said the Bills are not worried the injury "will jeopardize his season," but it is yet another issue for a receiver coming off a dreadful rookie campaign. With Jones out, the Bills have Kelvin Benjamin and not much else at receiver.
